The dialogues which have been translated in the first Appendix, and which appear to have the next claim to genuineness among the Platonic writings, are the Lesser Hippias, the Menexenus or Funeral Oration, the First Alcibiades. Of these, the Lesser Hippias and the Funeral Oration are cited by Aristotle; the first in the Metaphysics, the latter in the Rhetoric.
Neither of them are expressly attributed to Plato, but in his citation of both of them he seems to be referring to passages in the extant dialogues.
From the mention of 'Hippias' in the singular by Aristotle, we may perhaps infer that he was unacquainted with a second dialogue bearing the same name. Moreover, the mere existence of a Greater and Lesser Hippias, and of a First and Second Alcibiades, does to a certain extent throw a doubt upon both of them. Though a very clever and ingenious work, the Lesser Hippias does not appear to contain anything beyond the power of an imitator, who was also a careful student of the earlier Platonic writings, to invent.
